Embodiment
In order to make technical problem to be solved by this invention, technological scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Please with reference to Fig. 4 to Fig. 6; Be the embodiment one of water pump reliability testing of the present invention with belt pulley, this belt pulley comprises pulley body 1, and said pulley body is alms bowl shape; Said pulley body 1 has at least one trough of belt 11 along said pulley body 1 circumferencial direction; Like this, because belt pulley of the present invention is alms bowl shape, and has at least one trough of belt along said pulley body circumferencial direction; So can simulate the stressing conditions of cooling waterpump when in running order truly, thereby improve the accuracy of testing result widely.Below describe in detail.
In order to control the point of action of belt on belt pulley more accurately, so that the stress of simulated engine cooling waterpump more accurately, said trough of belt 11 is a V-shaped groove, and trough of belt 11 can only be established a V-shaped groove.Said trough of belt 11 is positioned on the said pulley body 1, near a side of said belt pulley opening, and position and the said water pump of said trough of belt 11 on said pulley body 1 be when in running order, the water pump belt is corresponding to the force application location of Water-pump belt wheel.Certainly, trough of belt 11 also can be other shapes, like circular groove or dovetail groove etc.
Certainly, when 11 of troughs of belt adopt a V-shaped groove, higher to the requirement of strength of belt; At this moment, the quantity of said trough of belt 11 is to be multiple tracks, like this; The belt that drives belt pulley can be poly Vbelt 28 (please with reference to Fig. 9); In this case, the active force of 28 pairs of belt pulleys of poly Vbelt is concentrated not as only adopting a V-shaped groove, but its point of action roughly equiv to the belt pulley active force is the middle part that is positioned at poly Vbelt 28.Belt in the present embodiment is a poly Vbelt.
Because in test process, belt is lax easily, for preventing the poly Vbelt slippage, in the said multiple tracks trough of belt 11 in the outside of outermost one trough of belt and the said multiple tracks trough of belt 11 inboard of one the most inboard trough of belt extend a blocked part 12 respectively.
For realizing installation, on the diapire of said alms bowl shape pulley body 1, be provided with some pilot holes 13 to the present embodiment belt pulley.In the present embodiment, the quantity of pilot hole 13 is 4 and is distributed on the diapire of pulley body 1.
For ease of installation, on the diapire of said alms bowl shape pulley body 1, also be provided with some and said pilot hole 13 auxiliary pilot hole 14 at interval to the present embodiment belt pulley.Because belt pulley need be installed on the water pump wheel hub, and wheel hub rotates, this makes the installation of belt pulley have certain difficulty, therefore needs to adopt auxiliary mounting hole 14.During installation, can use one or more pole to penetrate, and replace on the pump housing,, thereby create conditions for installing with the rotation of restriction wheel hub from auxiliary pilot hole 14.In addition, auxiliary pilot hole 14 also has the effect that alleviates belt pulley weight.
Please with reference to Fig. 7 and Fig. 8; Be the embodiment two of water pump reliability testing of the present invention with belt pulley; Compare with embodiment one; The size of present embodiment is less, and the position of trough of belt 11 is also different with embodiment one in the present embodiment, and this is because the water pump of different size has different stress (being that force bearing point and stressed size can be inequality to some extent) in practical work process.And on the other hand, the stressed size of belt pulley and cornerite (cornerite, be meant band and belt wheel contact arc right central angle) angle relevant, the force bearing point of belt is relevant with the position of trough of belt 11 on pulley body 1.Therefore, in order to realize real simulation, need to select suitable belt pulley to the water pump stressing conditions.Because the size of present embodiment is less, the pilot hole 13 on it and the quantity of auxiliary pilot hole 14 all can be less than embodiment one.
Please with reference to Fig. 9, be a preferred embodiment of water pump reliability testing test stand of the present invention, this water pump reliability testing test stand comprises power-driven system, pipe-line system, water pump mounting and clamping system, measurement and display control program.
In the present embodiment; Said power-driven system comprises motor 21, removably connected with said test stand by dibit belt pulley 22 that said motor 21 drives and two and in order to the belt pulley 23,24 of driving water pump; Belt pulley 23,24 can have the different techniques parameter so that simulate the stress of different water pumps; Its structure is same as the previously described embodiments, does not give unnecessary details at this.Certainly, the quantity of belt pulley can also be one or more.
In the present embodiment; Said water pump mounting and clamping system comprises water pump support 25; In order to realize accurate location to water pump; Also can between test stand water pump support 25 and water pump, establish base plate 26 is installed, realize cooperating between water pump wheel hub 27 and the dibit belt pulley 22 through the installation base plate 26 of selecting different-thickness.
Like this, the water pump reliability testing test stand of present embodiment just can be realized the test job to two water pumps simultaneously.And the belt pulley (promptly having different troughs of belt position and size) through selecting to have the different technologies parameter can be realized the real simulation to the water pump stress.Thereby improved the compatibility of water pump reliability testing test stand greatly.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
